Abstract
Various systems and methods are provided for reducing an amount of oil reaching a crankcase overpressure sensor. In one example, a system may include a cast wall protruding perpendicularly from an internal wall of crankcase, the cast wall at least partially surrounding a sensor port for a crankcase overpressure (COP) sensor, the sensor port fluidically coupled to the COP sensor via an internal passage; and a cover plate fixedly coupled to the cast wall, the cover plate parallel to the internal wall. In this way, oil may be blocked from reaching the COP sensor, while air may flow through the internal passage to the COP sensor.
Claims20
A system, comprising:
- a cast wall protruding perpendicularly from an internal wall of a crankcase of an engine, the cast wall at least partially surrounding a sensor port for a crankcase overpressure (COP) sensor, the sensor port fluidically coupled to the COP sensor via an internal passage;
- and
- a cover plate fixedly coupled to the cast wall, at least a portion of the cover plate parallel to the internal wall.
A system for a vehicle, the system comprising:
- a crankcase encasing cylinders of an engine, the crankcase including an integrated front end housing;
- a crankcase overpressure (COP) sensor coupled to the crankcase;
- a sensor port positioned in an internal wall of the integrated front end housing, the sensor port fluidically coupled to the COP sensor;
- a cast wall integrally formed with the internal wall, the cast wall at least partially surrounding the sensor port;
- and
- a cover plate fixedly coupled to the cast wall, at least a portion of the cover plate parallel to the internal wall.
A method, comprising:
- monitoring a crankcase pressure in a crankcase of an engine based on a signal from a crankcase overpressure (COP) sensor, the COP sensor coupled to an integrated front end housing of the crankcase, and a sensor port of the COP sensor at least partially surrounded by a cast wall and a cover plate.
